Revisiting and Enlisting Important QTLs Identified in Frech Bean (<em>Phaseolus vulgaris</em> L.): A Review

Abstract

French bean (Phaseolus vulgaris L.) a member of family Leguminosae is a useful source of protein (&amp;sim;22%), minerals (folate), vitamins and fibre. Abiotic and biotic stresses are the constraints to high yield and production of French bean. Varieties reluctant to diseases as well as abiotic stresses is among the top breeding objectives for the French bean. Mendelian ratios could know the genetically reliable forms of resistance, whereas it's more robust to understand the intricate kinds, often referred to as quantitative trait loci (QTL). Here, we review and compile the information from the studies related to the identification of QTLs for critical biofortification traits, biotic and abiotic stresses in French bean. Successful map-based cloning requires QTLs represent single genes which could be isolated in near-isogenic lines, and also the genotypes could be unambiguously inferred by progeny testing. Overall, this information will be useful for directing the French bean breeders to select a suitable method for the inheritance evaluation of quantitative traits and determining the novel genes in germplasm resources to ensure that much more potential of genetic information may be uncovered.

Effects of Biotic Stresses and Their Mitigation Strategies in Legumes: A Review

“…Insect herbivory and viral infections limit leaf area and hinder photosynthesis, while stress-inducing bacteria pose a threat to plant survival by disrupting nutrition delivery (Akram et al, 2021). Temperature fluctuations influence pest activity and reproduction, contributing to a significant 20% annual yield loss from pests and illnesses in legume crops (Dhaliwal et al, 2020). Particularly in Asia and Africa, leguminous crops can experience devastating losses of up to 100% under favorable biotic stress conditions (Singh et al, 2022).…”

“…According to published research, several food crops are susceptible to root rot diseases caused by Fusarium solani (Tembhurne et al, 2017), F. oxysporum (Chandra et al, 2019), Rhizoctonia solani (Patro et al, 2018) and Pythium species (Syed et al, 2020). However, M. phaseolinaresistant commercial cultivars have not yet been created, despite a few scientific attempts to identify the origins of resistance (Dhaliwal et al, 2020). Researchers discovered few resistance cultivars against M. phaseolina, the pathogen…”

A Brief Perspective on the Use of Bio-inoculants in Horticulture

“…As a consequence, the normal microbiome component of each crop species is yet unknown. While certain microorganisms that interact with plants are thought to be harmful, a large number of bacteria that inhabit plant markets may demonstrate neutral or even positive traits at times [37][38][39][40][41][42][43][44][45][46][47][48][49][50].…”
